If you're looking for a quick handout that covers the levels of protein structure, helps students identify the parts of a nucleotide, or even lists the abbreviations for amino acids, we can help.  

BLAST is one of the most powerful tools in modern biology.  This collection of programs can be used to identify the origin of unidentified DNA sequences and predict the function of unknown proteins.  The BLAST tutorial goes through the steps involved in comparing a DNA sequence to a collection of sequences in a database and evaluating the results.  This tutorial is accompanied by a set of 16 unidentified sequences from a variety of organisms ranging from viruses to humans. 

This glossary and worksheet were made to accompany the Molecule World DNA Binding Lab iPad app.  Now with nucleotides, too!  

A quick review of the levels of protein structure. This handout shows the primary, secondary, tertiary, and quaternary levels of protein structure, made with images from molecular models. The handout also describes the kinds of bonds that are most important in each level of structure. Useful for studying proteins in biology, biochemistry, bioinformatics, genetics, molecular biology, and microbiology.

This learning activity is designed to help students use molecular structure images without the molecular-viewing software. Students work with images from Cn3D on paper (or on screen as a pdf document) to identify nucleotides, base pairs, and parts of nucleotides. If you’re an instructor, you can also use the image page as a quiz. If you’re a student, this is a great way to learn about the four bases in DNA and review their structure.
